PH automatic dosing device works because the water treatment process requirements, PH value of water often needs to be controlled within a certain range of PH value, to the water, adding acid or base to meet this requirement is the most direct and effective way. Commonly used acid and alkali neutralizing agents include sulfuric acid, hydrochloric acid, ammonia, sodium hydroxide, calcium hydroxide, sodium carbonate and the like. Detected by the line pH sensor and pH value of the pool or chemical reaction kettle liquid and transfer to pH monitoring device, according to production requirements, the pH monitor is set high, low control point automatic dosing device, pH monitor pH signal input after and high and low set value output switching signal or proportional control signal to the control box, the control box to adjust the amount of control the metering pump acid or alkali amount. The system does not require personnel to operate, automatic control, automatic dosing device spot, thus greatly improving the accuracy and efficiency of dosing, and ensure safe production and stable processes and personnel. Automatic dosing device process principle of automatic dosing device is an intelligent, automatic, continuous integration solution with powder and dosing devices. The device consists of water supply systems, powder dosing system, dissolve curing systems, automatic control system structure. The device is fully automatic continuous configuration and powdered medicament dosing system. Dry powder from a hopper into the lower portion of the auger premix is ??premixed with the water, the wet material was formulated into the mixing tank for dilution, the concentration of formulated according to user requirements; preparation of the solution from the preparation tank through a storage tank into the aging tank and then automatically Dosing devices offer, when a storage tank at a high level, the preparation process automatically stops the integration of automatic dosing unit, when the solution falls to a low level, the automatic start blending process. Preparation and aging groove slots are set stirrer, diluted and fully guarantee the curing agent. Preparation of flow and concentration can be determined by adjusting the water flow and adjust the screw shaft speed. This device is a PLC control system with a high degree of automation, stable performance, simple operation. Automatic dosing device consists of the following components of water supply systems, powder dosing system, dry premix system, desiccant systems, integration of the Triple combination box, mixing system, automatic control and detection systems integrated automatic dosing device _ Zhongshan _ automatic dosing device provided rich students from Guangzhou Environmental Protection Engineering Co. rich students.
